Harry Potter
The Glenfinnan viaduct, pictured here, is the most impressive concrete railway bridge in all of the Harry Potter Universe, and more importantly, in Scotland. It spans over 415 miles altogether. You might recognize it from the fourth "Harry Potter" flick when the students made their yearly trek to the enviable Hogwarts School of Witchcraft and Wizardry. To see it for yourself, head on over and take a ScotRail passenger train on the West Highland Line.
